Patent CA-2196836-C (CA)
Title: Underwater cable burial machine having tripable plows
Inventor: GARREN DONALD LEE
IPC: E02F5/10
Filed: 1997-02-05
Granted: 2000-12-19
Abstract: A cable burying machine having three plow blades which are mounted on a rotating disk. The disk is restrained from movement in normal operation, but if the active plow blade encounters an obstacle which imposes more than a preset force on the blade, the disk will automatically rotate, preventing damage to the blade, and bringing the next blade into position. A remotely operable tripping mechanism can be used to reduce the amount of resistance to rotation which was preset, thereby allowing an operator on a surface vessel to command a plow rotation to remove debris from the active plow blade.

Abstract: A radio telephone which is capable of switching between operating through a land-based cellular network and an orbiting satellite system is disclosed. First antenna and radio frequency circuits receive transmitted signals from the land-based network and form first conditioned signals for subsequent numerical decoding. Second antenna and radio frequency circuits receive transmitted signals from the orbiting satellite system and form second condition signals for subsequent numerical decoding. Numerical decoders process either the first condition signals or the second conditioned signals to provide an automatic frequency control signal. Reference frequency oscillators controlled by the automatic frequency control signal provide a reference frequency signal. Radio frequency synthesizers using the reference frequency signal and having a first output at a first programmable frequency connected to the first radio frequency circuits determine reception of a channel frequency of the land-based network and a second output at a second programmable frequency connected to the second radio frequency circuits determines reception of a channel frequency of the orbiting satellite system.

Abstract: Fluidic constructs, including grouped stacks of fluidic elements, that provide countersound to control sound in a noisy environment, prevent radiation of sound from vibrating surfaces, reduce sound-induced vibration of surfaces, and absorb sound that might otherwise impact on surfaces, are provided. These constructs may have a wide range of geometries for specific applications, but generally include a face plate on one side, and a back plate on the other side. Supply ports on the back plate provide a supply of fluid that flows through the construct, while undergoing acoustic modulation through fluidic amplifiers. The face plate includes input ports that sense sound waves to be controlled, and transmits this sound to influence the acoustic modulation of the supplied fluid. The construct produces an amplified output, having sound out of phase with the sound sensed by the input ports, at output ports on the face plate in a sufficient volume to substantially neutralize incoming sound waves, or reduce sound radiation from an object. Any sound produced by the construct of the invention that is substantially in phase with sound to be neutralized is dumped at a sufficient distance from the produced countersound to minimize interference.

Abstract: A reception signal (x(n)) is input to an echo generator system  (1). An observation signal  (z(n))  is gathered  from  the  system.  The  reception  signal  is filtered to produce an echo prediction signal (y(n)). The echo prediction signal is subtracted from the observation signal to produce an error signal (e(n)). The observation signal  (z(n))  is decomposed into M spectral components relating to different frequencies of the spectrum.  M corresponding spectral components of the echo prediction signal (y(n)) are obtained. M quantities, each having a value with progressive  variation representative  of  a degree of similitude between, respectively, one of the M spectral components of the observation signal and the corresponding spectral component of the echo prediction signal, are calculated. At least one spectral shaping of the error signal (e(n)) is carried out as a function of these  M  calculated  quantities  so  as  to  adapt  the filtering and/or to deliver the output signal from the echo canceller.

Title: Safety coupling for rotary pump
Inventor: MILLS ROBERT A R
IPC: F16D7/04
Filed: 1998-05-11
Granted: 2002-08-20
Abstract: A safety coupling for preventing backspin at excessive speeds of a torque transmitting drive powering a drive string which stores reactive torque due to torsional stress. The safety coupling includes a rotatable driving member to be coupled with a torque producing power source, a rotatable driven member to be coupled with the drive string for axial rotation therewith. The driven member is movable relative to the driving member between an engaged position wherein the driving and driven members are coupled by a torque transfer structure to provide a positive driving connection between the torque transmitting drive and the shaft, and a disengaged position wherein the driving and driven members are freely rotatable relative to each other so that back-spin of the torque transmitting drive is prevented. The driven member is biased into the disengaged position and forced into the engaged position only during forward rotation of the shaft. To start rotation of the shaft, the coupling further includes an auxiliary coupling component which transfers a selected torque between the driving and driven members for start-up of the shaft from standstill and to force the driven member into the engaged position. However, the amount of torque transmitted by the auxiliary coupling component is less than the torque required for build-up of sufficient reactive torsion to create a potentially hazardous back-spin. Thus, the auxiliary coupling component is disengaged before potentially dangerous levels of reactive torsion are stored in the shaft, which prevents potentially hazardous back-spin, should the main coupling components of driving and driven member and torque transfer structure fail. The coupling substantially prevents damage to the torque transmitting drive upon excessive back-spin of the drive string and reduces the risk of injury to personnel working in the vicinity of a drive string storing elastic torsion. The coupling is preferably part of a safety arrangement including the coupling, a brake for slowing back-spin of the shaft created upon interruption of power to the shaft, and a common control member for controlling both the operation of the coupling and the brake.

Abstract: The present invention relates to safety joints which permit separation of a downhole assembly at the location of the joint. The invention provides a safety joint characterised by the provision of auxiliary interconnecting means on a body (2) for interconnecting said body (2) to an auxiliary shaft after removal of a main shaft (3) from said body (2). Axial loading between the auxiliary shaft and said body (2) may be thereby transferred. Furthermore, torque may also be transferred between the auxiliary shaft and said body (2) in a direction opposite to that in which torque may be transferred from the main shaft (3) to said body (2). Thus, the present invention allows a length of downhole assembly located above said body (2) to be removed from a wellbore by rotation of said length of assembly in a first direction and then allows rotation of said body (2) in the same first direction by means of the auxiliary shaft in an attempt to remove a length of assembly stuck in the wellbore downhole of said body (2).
